T 0 all whom it may concern.

Be it known that I, MATTIE L. J ONES, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented new and useful Improvements in Self-Raising WVindows, ofwhich the following is a specification.

This invention relates to improvements in windows and especially withreference to the provision of means for raising a sash and also forsecurely locking the sash when the same is in lowered position, theobject of my invention being to provide improved sash raising andlocking devices which are simple in construction and which can bereadily installed at small cost.

With the above and other objects in View, the invention consists in theconstruction, combination and arrangement 3 of devices hereinafterdescribed and claimed.

In the accompanying drawings Figure 1 is an elevation, partly insection, of a window provided with sash raising and locking meansconstructed and arranged in accordance with my invention.

Fig. 2 is a detail perspective view of the latch or looking shaft andits connections.

For the purposes of this specification, a window frame is indicated at 1and a sash'is indicated at 2. The sash is provided at opposite sides andnear the bottom with outwardly extending lugs 3 which operate in thesides of the window casing. I also provide pulleys t which are mountedfor rotation as at 5 and are arranged in the sides of the window casingand at a suitable distance from the base thereof. Cords 6 for raisingthe sash are attached to the lugs 3 and pass over the pulleys. Coiledretractile springs 7 are arranged; in the sides of the casing, havetheir lower ends secured as at 8 and have their upper ends attached tothe cords as at 9. The said .the lugs 3.

springs coact with the cords and the pulleys to raise the sash when thelatter is released, as will be understood, so that the sash in effect isself raising. In order to securely fasten the sash when the same is inlowered position and thus make the window secure I provide a shaft 10which is mounted in bearings 11 in the base of the window frame orcasing and is provided at the ends with latches 12 which are adapted toengage over One of the latches is formed with an outwardly extending arm13 which projects through a slot in the base of the window casing andwhich may be manually actuated to turn the shaft to either looking orunlocking position.

hile I have herein shown and described a preferred embodiment of myinvention, I would have it understood that changes may .be made in theform, proportion and construction of the several parts within the scopeof the appended claim and without departing from the spirit of myinvention.

Having thus described my invention, I claim:

The combination with a self raising window having lugs projecting on theopposite sides thereof and movable within a space in the window casing,of a transversely eX- tended shaft journaled within the window sill andhaving its ends projecting from opposite sides of the sills within thespace of the window casing, a hook like element carried by each end ofsaid shaft exterior-1y of the window sill, said hooks being normallydisposed vertically for engagement with said lugs to hold the window inlowered position, and a finger projecting from said shaft at a rightangle to one of said hooks, said finger being adapted to be depressed torock said shaft and release said window.

In testimony whereof I aflix my signature.
